Unveiling the Power of Calcined Kaolin in Ceramic Production
What is Calcined Kaolin?
Calcined kaolin, often known as "china clay," is a key ingredient in the ceramics industry. It is derived from the raw kaolin mineral, which is heated at high temperatures to transform it into a more useful form. The process of calcining not only improves the kaolin's physical and chemical properties but also makes it suitable for various ceramic applications.
The Journey of Kaolin to Calcined Kaolin
1. Mining and Processing
Our journey begins at the mining site, where raw kaolin is extracted from the earth. At Hebei Glory Star Group, we pride ourselves on using the highest quality kaolin from Lingshou County, the cradle of non-metallic minerals. Once extracted, the kaolin is processed to remove impurities, leaving us with a pure material.
2. Grinding
Next, the processed kaolin is ground into a fine powder. This step is crucial as it ensures that the kaolin particles are small enough to mix evenly with other ceramic materials.
3. Calcining
The final and most transformative step is calcining. This involves heating the kaolin to temperatures ranging from 900°C to 1200°C. The heat drives off moisture and volatile components, resulting in a denser, more stable material. At Hebei Glory Star Group, our advanced calcining kilns ensure a uniform heating process for the best quality calcined kaolin.

2. Excellent Thermal Expansion
One of the standout features of our calcined kaolin is its exceptional thermal expansion properties. This makes it ideal for use in ceramic products that require high heat resistance, such as tiles and porcelain.
3. Good Plasticity
The plasticity of calcined kaolin allows for easy shaping and molding during the ceramic manufacturing process. This results in high-quality, uniform ceramic products with minimal defects.
Applications in the Ceramic Industry
1. Tile Manufacturing
Calcined kaolin is a staple in the production of ceramic tiles. Its excellent thermal expansion properties and high purity make it ideal for creating tiles that are both durable and aesthetically pleasing.
2. Porcelain Production
In the porcelain industry, calcined kaolin plays a crucial role in providing the necessary strength and stability to the final product. Its high purity ensures that porcelain products are free from impurities that could compromise their quality.
3. Whitewares
Whitewares, such as dinnerware and toilet fixtures, benefit from the natural white color and high purity of calcined kaolin. This helps in creating products that are visually appealing and hygienic.
